IMPROVEMENT IN CHURNS..

Specification forming partof Letters Patent No. 13,44. dated August 16, 1864.

To all whom it may concern:

Be it known that we, DANIEL FnEY and DELos SANDERS, both of Homer, county of Cortland, and State of New York, have invented a new and Improved Churn; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, mak'ng a part 'of this specilicatiomin which- Figurel is a diameirical section through the churn bix, tubular collar, and pinion spur wheel, the parts being adjusted for giving motion both to the dasher and the beater. Fig. 2 is a vt rlir al section through the churn, taken at right angles to the section of Fig. il. Fig. 3 is a top view of the driving-gear. Fig` 4 is a top view of the pinion spur-wheel and collar surrounding the staff of the dasher.- Fig. 5 is a vertical section through Fig. 4, showing the pinion-wheel in two positions.

Similar letters of reference .indicate corresponding parts in the several gures.

By our invention and improvement in churns we are enabled to employ revolving beaters in conjunction with a centrally-reciprocating dasher, and to give motion to both of these devices at the same time, or, if desirable, to either one separately, by a simple manipulation and without removing any ot' the parts from the machine, as will be hereinafter described.

To enable others skilled in the art to make and useour invention, we will describe its construction and operation.

The cylindrical churn-box A may be constructed in any suitable manner and of any convenient size, and the top or cover of this box may be made of two semicircular parts and secured in place by means of buttons, hooks, or equivalent devices. On the inside of the box A, and secured thereto in upright positions, are a number of ribs, a a., the exposed surfaces of which may be made concave or in any form whereby the cream, dashing against them, will be thrown off toward the middle of the box A.

B represents a bracket having` a square hole through it, and supported, by means ot' arms a' a', over a central opening through the churn-cover (l. On top of this bracket B, and projecting up perpendicularly therefrom,we rigidly secure a forked standard, B', which, together with the said'bracket, form a central guide for the staff D of the dasher D', and,

while they allow the staff to move up and down freely, they keep this stati' in its upright position coincident with the center of the churnbox.

The dasher B', which is secured on the lowermost end of the stad' B, consists of a perforated disk having short pieces of wood secured at regular intervals around its periphery, as clearly shown in Figs. 1 and 2.

At or near the upper end of the dasherstaff D a box, b, is secured by means of a removable pin, b', which box has a pin, b2, projeoting horizontally from it, which receives one end of a pitman, c, the opposite end of which is pivoted eccentrically to the large driving spur-wheel E. The shaft of the Wheel E is supported in a horizontal position by the standards c' c', which are secured to one-halfl of the churncover C, and on the outer end ot' said shaft-a hand-crank is keyed, by turning which a vertical reciprocating movement will be communicated to the staff D and the dasher D' in the churn-box. 'l` he driving spur-wheel E engages with a horizontal pinion, f, which is formed with a tubular hub or collar, d, projecting up from its face and having a vertical slit, e, through it, terminating inside ofthe wheel's center in a slot or groove. The concentric tubular opening through the bevel spur-wheel F receives a tube or thimble, G, the tube of which is somewhat longer than the hub or collar d, which surrounds it for the purpose of allowing the wheel F to be adjusted thereon when it is desired to engage (or disengage) this wheel with the drivingwheel E, as will be hereinafter explained. The lower end of the thimble G has a flange surrounding it, through which the screws pass that secure the horizontal arm f of the beater to said thinible, and the upper end of said thiinble is held in place, though allowed to rotate in the bracket-box B, as shown clearly in Fig. 2. The two beater-arms f and f' are connected together by means of open or slotted slats g g, which revolve around the dasher D', and this beater is supported and kept in place at its lower end by means of a central pin, h, the axis of which coincides with that of the wheel F, and the square staffl which we have above described. The wheel F, when it is in gear with the wheel E, is kept in place and supported by a pin, t', that projects from the thimble G and enters a notch formed in the bottom of this wheel F, as shown in Figs. l,

2, and 4; but when it is desired to stop the motion of the dasher the wheel F is lraised sni'iieiently far to disengage it from pin i, and then turned until this pin will enter the slot e, when the wheel F will drop down, as indicated in red lines, Fig. 5, out of the way of the driving-wheel, anfl the beaters will remain` stationary while the flasher is moved.

To reverse the order and move the beaters while the dasher is stationary, it is only necessary to raise the flasher to its highest point, remove the pin b from box b and insert this pin through thc hole b3 in the stan" D, so that said pin will rest on top of the forked standard B. The box b will now play up and down without moving the dasher. .The beaters are set in motion by engaging the wheel F with E, and also with the thimble G, that is secured to the heater-'arm j', as represented in Figs. l and 2. y

The operation of the beaters anfl dasher is as follows: AsY the flasher descends the cream is forced upward and outward At the same time the beaters, which are revolving around the flasher at the commencement of the operation ofchurning, pass rapidly through the outwardly-flowing cream, and, with the assistance of the beveled or concave slats or ribs ft a, throw the cream back again toward the center of the churnbox, to be similarly acted upon as the dasher rises.

rEhe driving mechanism is or may be applied to one 'ha-lf of the churn-cover, so that the l other haltimay be readily removed for inspectbeater, as the shape of these parts may be very materially varied, still the slatted flasher and slotted beater will be found very efficient in producing the butter from cream.

We do not claim, broadly, a churn having a dasher and abeater, one of which has a reciprocating movement and the other a rotatory motion, dependent upon each other, for this is not new. y

What we claim as new is- 1. The use of a shifting pinion, F, or its equivalent, in combination with devices applied to the flasher and beaters for driving them, substantially as described;

2. Communicating a reciprocating motion to Ithe flasher through the medium of aflrilvingwheel, E, shifting-pinion F, pin i, and thimble Gr, substantially as described.

3. The pivot bearing-box b and removable p in b', applied to the staff of the dasher, substantially as and for the purposes described.

Witness our hands and seals, in the matter of our application i'or a patent on an .improved churn, this 9th day of March, 1864.
